Here are some pics taken with mirrors, prisms, fan diffraction gratings, and some new gratings I got in Offroads last group buy. Also in the group buy I got some pen tripods which have a clamp that keeps a pen lasers on/off button depressed, making life much easier. Also some decent pics with 589nm, 593.5nm and 473nm. Enjoy
